Struct BytesNarSource 

pub struct BytesNarSource { /* private fields */ }

A NarSource over bytes already in memory.

Zero-copy: Bytes slices share one allocation, so re-opening does not duplicate the NAR. It is still O(nar) resident by construction — that is the point of the name. Use it for test doubles, for small values, and at a boundary that genuinely already holds the bytes; never as the way a large upload reaches a backend.

Implementations

impl BytesNarSource

pub fn new(bytes: impl Into<Bytes>) -> BytesNarSource

Wrap owned bytes.

Trait Implementations

impl Clone for BytesNarSource

fn clone(&self) -> BytesNarSource

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BytesNarSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<&[u8]> for BytesNarSource

fn from(v: &[u8]) -> BytesNarSource

Converts to this type from the input type.

impl NarSource for BytesNarSource

fn size_hint(&self) -> Option<u64>

Total byte length if it is known before reading. Backends use it to size a multipart upload or to reject an over-cap value before reading a single byte; None is always legal and must never be load-bearing.

fn open<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = Result<Bytes, StoreError>> + Send>>, StoreError>> + Send + 'async_trait>>

where 'life0: 'async_trait, BytesNarSource: 'async_trait,

Open a fresh chunk stream over the same bytes.
